Can somebody help me with this? I have to find the quadratic spline $s_Q$, when I know: $$ i = 1 \quad 2 \quad 3 \quad 4 $$ $$ x_i = −1 \quad 1 \quad 2 \quad 3 $$ $$ y_i = −2 \quad 0 \quad −1 \quad 0 $$ and $s_Q'(x_4) = 1$.
And I have to find cubic spline $s_C$, when I know: $s_C''(x_1) = 0$, and $s_C'(x_4) = −1$.
